16:4.6
Much of the reality of the spiritual worlds is of the morontia order, a phase of universe reality wholly unknown on Urantia. The goal of personality existence is spiritual, but the morontia creations always intervene, bridging the gulf between the material realms of mortal origin and the superuniverse spheres of advancing spiritual status. It is in this realm that the Master Spirits make their great contribution to the plan of man’s Paradise ascension.
